China-Western Australia Seismic array

This is a temporary broadband seismic array along the northwestern coastal region of Western Australia, operated by Macquarie University, Geological Survey of Western Australia, and the Institute of Geology and Geophysics, Chinese Academy of Sciences. The target is the lithospheric structure of this part of Australia, whose formation and evolution history spans from ~3.2 Ga to very recent during the Neo-Tethys ocean opening ~140 Ma. There are two phases of the deployments of linear arrays, both are already finished. In total there were 60 sites.
